Problem 65. Word Counting and Indexing

You are given a list of strings, each being a list of words divided by spaces. Break the strings into words, then return a master word table of all the words and an indexed version of each string.
The master list should have no repeated entries and should be sorted in alphabetical order. The index list must be an array cell of index of each cell member corresponding to the same value in the master list.
For Example
If str_list = {'one two three','two one four zero'}
  • word_table = {'four','one','three','two','zero'}
  • str_index_list = {[2 4 3],[4 2 1 5]}.
Notice that no words are repeated in word_table, and each string in the string_list can be regenerated by referencing into the word_table using the string_index_list.
